what is the one tertiary amine with the molecular formula C4H11N?
The correct answer and explanation is:
The compound with the molecular formula C4H11N that is a tertiary amine is N,N-dimethylpropanamine (also known as N,N-dimethylpropylamine).
Explanation:
A tertiary amine is an amine in which the nitrogen atom is bonded to three alkyl or aryl groups. In this case, the nitrogen in N,N-dimethylpropanamine is attached to a propyl group (C3H7) and two methyl groups (CH3).
Molecular Formula Breakdown:
- C4H11N means the compound contains four carbon (C) atoms, eleven hydrogen (H) atoms, and one nitrogen (N) atom.
- The carbon atoms in the molecular structure are arranged to form a propyl group (C3H7), which is a three-carbon chain, and two additional methyl groups (CH3), which are one-carbon chains. These methyl groups are attached to the nitrogen, making it a tertiary amine.
Structure:
The structure of N,N-dimethylpropanamine is as follows:
- A propyl group (C3H7) is attached to the nitrogen atom.
- Two methyl groups (CH3) are attached to the same nitrogen atom.
Thus, the nitrogen is bound to three different alkyl groups, making it a tertiary amine.
IUPAC Name:
The IUPAC name for this compound is N,N-dimethylpropanamine, where:
- “propanamine” indicates the propyl group attached to the amine.
- “N,N-dimethyl” shows that two methyl groups are attached to the nitrogen atom.
This compound is used in various chemical applications and is a common structure in organic chemistry. Tertiary amines are often involved in nucleophilic substitution reactions and other organic transformations.
